Why is it that so few diet products are backed by science? Let’s find out if Jen Fe Next is one of the good ones. We took the time to create an in-depth review, examining the side effects, ingredients, clinical studies and level of customer service. Plus we sorted through all sorts of user comments and remarks that are posted online. At this point, we compacted all of the facts and feedback we found to give you the info you really need.

What is Jen Fe Next?

To start, Jen Fe Next ingredients include guarana, chromium picolinate, coleus forskohlii and cosmoperine. This product is marketed as a fat loss patch. It’s boasted as “weight management made simple.” You simply apply one patch each day, and the ingredients are released through the skin and into the bloodstream. It’s claimed to curb food cravings, boost energy levels, burn off fat and even increase muscle tone. No special diet or exercise is required.

We are not sure when the Jen Fe Next patch was first released. However, the company behind this weight-loss product is Nexagen USA, LLC, which is located in Akron, OH. This product is supposed to help you drop one to four pounds each week. Furthermore, it is sold with a 40-day money-back guarantee, but read on…

Side Effects – “Is It Safe?”

The first concern we have is with Jen Fe Next side effects. “Some customers have reported unpleasant reactions like jitteriness, heart palpitations, nausea, headache, anxiety and dizziness,” says our Research Editor.

According to one user, “Don’t like these Jen Fe Next patches. Makes me very nauseated and jittery. Not cool. Had to stop using this.”

However, a different customer reported, “Not sure at this point. I have not changed my diet or lifestyle. It may be working, but I will have to give it more time to really see.”

Another commented, “It does not seem to have any effect on me. Oh well. It was worth a shot. I would like my $70 back though.”

User Complaints – “Something Else to Consider”

Unfortunately, we did find several user complaints posted on the web for Jen Fe Next patches. In fact, one person said, “This does not work at all. Tried it for the full 30 days and nothing.”

But, a different person revealed, “I think it helps curb my food cravings. It gives me a slight caffeine buzz as well.”

“Going to have to give it more time. It’s been a week so far. I think it gives me an energy boost,” stated another user.

The extensive research we’ve done has shown if there’s a certain aspect of a diet product or weight-loss program that’s quite troublesome (side effects, user complaints, poor BBB rating) the probability of long-term success is low. So, if Jen Fe Next does in fact lead to unwanted adverse reactions in a lot of people, this could be problematic.

The Science – “Is There Any?”

First off, we appreciate that Jen Fe Next contains some herbal ingredients like guarana and coleus forskohlii. However, we could not pinpoint any actual studies that support this weight-loss patch. This is concerning, because we at DietSpotlight prefer to see some solid science that backs up the product we’re investigating.

The Bottom Line – Does Jen Fe Next Work?

So, should you race out to the store and buy Jen Fe Next? Well, we like that this weight-loss patch is easy to use and only needs to be applied once a day. It’s also nice to see that this product contains natural herbs. However, we have some reservations about it because it’s not supported by any documented studies or research. Also, we’re concerned about the side effects some users have reported. Not to mention, there is a Better Business Bureau “alert” on the company.

If you’d like to drop more weight, then we encourage you to go with a diet product that is backed by real science, does not cause any harmful side effects and is sold by a reputable company that is not under any scrutiny.

Among the best products we’ve seen this year is one called Leptigen. This unique formula offers a blend of four potent ingredients, some of which have been clinically tested and are shown to help speed up fat loss and elevate metabolism. The company has earned a good rating with the BBB and harmful side effects are not part of the experience.

The makers of Leptigen are so sure about their product they’re offering a Special Trial Offer, which is a positive sign.

Nexagen also offers a common-sense lifestyle modification program free to anyone who purchases the Jen Fe Next patch.

List of Ingredients

Asian Guarana (Pia cupana),ChromeMate (Chromium polynicotinate) ForsLean® (an extract of the herb Coleus forskohlii) Cosmoperine® (tetrahydropiperine)  

Product Features

The Jen Fe Next Patch formula combines the following elements for maximum weight loss benefits: ForsLean® (extract of Coleus forskohlii) a thyroid stimulant,ChromeMate® (chromium poly-nicotinate), the natural form of chromium, an appetite suppressant which aids the body in burning calories. Guarana, a natural source of caffeine which increases adrenalin to boost blood sugar and energy, Cosmoperine® a combination of the active ingredient in black and long peppers and thyreodinum extract which increases the transdermal uptake without causing skin irritation. In a clinical study conducted by Nexagen, using the double blind placebo method, results that the active group (given the actual patch) lost 68% more weight and lost 44% more in waist size than the placebo group (given a placebo patch).

  • The official website has a lot of information available for each ingredient.
  • A weight loss patch may appeal to those who don't like swallowing tablets or capsules.


  • A 30-day supply of the Jen Fe Next Patches costs $69.95.


The Jen Fe Next Patch seems like a great idea. Many other pharmaceuticals come as patches these days whether it's for chronic pain or to stop smoking so it's only natural a weight loss product would follow suit. We aren't really sure how well all of the ingredients in weight loss patches are absorbed into the skin and there isn't any data available on it either. We recommend sticking with a weight loss capsule that contains a powerful thermogenic unless you have severe trouble swallowing pills.

It’s sadly funny how the majority of the “hate on Kate” comments are coming from women. No wonder most women over the age of 35 are alone and single. Extremely nosey, set in their ways, and definately on the pissy side. Just take her words as inspiration and get on with our lives.
